Description

本発明は、特に、内燃機関に用いられる、多部分構成とした排気管を封止する封止システムに関し、この封止システムは、熱流をガイド（放熱）する少なくとも第１および第２のフランジ部を備え、これらフランジ部間に少なくとも１個のシール素子を収容するための受容空間を画定する。   The present invention particularly relates to a sealing system for sealing an exhaust pipe having a multi-part configuration used in an internal combustion engine, and the sealing system includes at least first and second flange portions for guiding (dissipating heat) heat flow. And defining a receiving space for accommodating at least one sealing element between the flange portions.

このような封止システムは既知である。例えば、特許文献１（独国特許出願公開１０２００４０６０８４５号）は、ピストンエンジンの排気管用の封止システムを記載している。この封止システムは、シール素子として、Ｃ字状の断面輪郭を有する金属製のシールリングを備える。排気管路のシール素子は、場合によっては６００゜Ｃを超えるような極度の高温に晒される。作動温度が通常高温である場合、シール素子は、たとえ耐熱性に関して特別な性質を有する材料を使用したとしても、封止に必要とされる機能特性を失う。特に、シール素子の弾性は、過度の熱応力により生じるクリープ過程を経ることで劣化してしまう。   Such sealing systems are known. For example, Patent Document 1 (German Patent Application Publication No. 102004060845) describes a sealing system for an exhaust pipe of a piston engine. This sealing system includes a metal seal ring having a C-shaped cross-sectional profile as a sealing element. The exhaust line seal element is exposed to extremely high temperatures, possibly exceeding 600 ° C. If the operating temperature is normally high, the sealing element loses the functional properties required for sealing, even if a material having special properties with respect to heat resistance is used. In particular, the elasticity of the sealing element deteriorates through a creep process caused by excessive thermal stress.

独国特許出願公開１０２００４０６０８４５号公報German Patent Application Publication No. 102004060845

したがって、本発明の課題は、高温ガス領域で使用しても、また、封止すべき排気管が高温に晒されても、確実に封止を保証できる封止システムを得ることにある。   Therefore, an object of the present invention is to obtain a sealing system that can reliably ensure sealing even when used in a high temperature gas region or when an exhaust pipe to be sealed is exposed to high temperatures.

この課題は、請求項１に記載する特徴を備えた封止システムにより達成される。   This object is achieved by a sealing system with the features as claimed in claim 1.

この構成により、本発明封止システムは、互いに隣接してシールし合うフランジ部が、熱流に直交してこれから離れる外方に突出するリング状フランジを形成し、このリングフランジに、シール素子のためのチャンバを形成し、リング状フランジの材料自体が、熱流からシール素子を確実に保護することを特徴とする。さらに本発明によれば、リング溝内に収容したシール素子を、カバー素子により保護し、このカバー素子は、リング溝内でシール素子の少なくともフランジ部材の端面側において断熱体を構成する。このように、シール素子は、最も熱負荷が過酷なリング溝の開口側において、特に効果的に熱負荷に対して保護する。このため、本発明に係る封止システムは、大きな熱負荷に晒される排気管に適用しても、確実に機能する。   With this configuration, the sealing system of the present invention forms a ring-shaped flange in which the flange portions that are sealed adjacent to each other project outwardly perpendicular to and away from the heat flow. The material of the ring-shaped flange itself ensures that the sealing element is protected from heat flow. Furthermore, according to the present invention, the sealing element accommodated in the ring groove is protected by the cover element, and this cover element constitutes a heat insulator in at least the end face side of the flange member of the sealing element in the ring groove. In this way, the sealing element protects against the heat load particularly effectively on the opening side of the ring groove where the heat load is the most severe. For this reason, even if it applies to the exhaust pipe exposed to a big heat load, the sealing system which concerns on this invention functions reliably.

好適には、カバー素子として金属製のリング体を設ける。   Preferably, a metal ring is provided as the cover element.

平坦リングの形態をとるリング体を用いる場合、好適には、リング体は、シール素子とフランジ部の端面との間に延在するように配設して、シール素子が収容されるリング溝のうち、最も大きな熱負荷に晒される領域を保護する断熱体を構成するようにする。   When a ring body in the form of a flat ring is used, the ring body is preferably arranged so as to extend between the seal element and the end face of the flange portion, and the ring groove in which the seal element is accommodated is preferably disposed. Among them, a heat insulator that protects an area exposed to the largest heat load is configured.

カバー素子は、平坦リング体でなく、断面輪郭がアーチ状または山形を成すリングにより構成してもよい。   The cover element may be constituted by a ring whose cross-sectional contour forms an arch shape or a mountain shape, instead of a flat ring body.

好適には、この種の実施形態においてリング体は、リング溝内で、シール素子をその端面側と収容空間の他の壁側とにおいて保護するように配設する。   Preferably, in such an embodiment, the ring body is arranged in the ring groove so as to protect the sealing element on its end face side and on the other wall side of the receiving space.

特に好適にシール素子を断熱保護するのに適した実施形態において、カバー素子は、シール素子の熱流に最も近い側、つまり、リング溝の半径方向内方の壁側も保護する。   In an embodiment particularly suitable for adiabatic protection of the sealing element, the cover element also protects the side closest to the heat flow of the sealing element, ie the radially inner wall side of the ring groove.

好適には、シール素子として、特に断面輪郭がＣ字状またはＶ字状である金属製の成形リングシールを用いる。このとき、断面輪郭がＣ字状のシール素子の開口部は、リング溝内で半径方向内方、つまり封止システムのスラスト面に向かって開口するように配設する。   Preferably, a metal molded ring seal having a C-shaped or V-shaped cross section is used as the sealing element. At this time, the opening portion of the sealing element having a C-shaped cross-sectional profile is disposed so as to open radially inward in the ring groove, that is, toward the thrust surface of the sealing system.

シール素子の断面輪郭を、Ｖ字状またはＣ字状とする代わりに、ベローズ体ような互いに重なり合う折り畳み片が断面輪郭をなすような蛇行形状としてもよい。   The cross-sectional contour of the sealing element may be a meandering shape in which folded pieces that overlap each other, such as a bellows body, form a cross-sectional contour instead of being V-shaped or C-shaped.

代案として、収容空間内には、金属製の波形シールをもることができる。いずれにせよ、本発明は、それぞれのシール素子に断熱保護を与えることが可能であり、このため、高熱での適用が可能な材料からなる金属製のシール素子によって、高温ガス領域でも確実に封止可能となる。シール素子のリング形状は、円形、またはほぼ円形とすることができる。さらに、楕円や、好適には角を丸めた長方形とすることも考えられる。このときリング溝の形状は、好適には、各シール素子のリング形状に従うものとする。   As an alternative, a metal corrugated seal can be provided in the receiving space. In any case, the present invention can provide thermal insulation protection to each sealing element. Therefore, a metal sealing element made of a material that can be applied at high temperature ensures sealing even in a high-temperature gas region. It can be stopped. The ring shape of the sealing element can be circular or nearly circular. Furthermore, an ellipse or preferably a rectangle with rounded corners is also conceivable. At this time, the shape of the ring groove preferably conforms to the ring shape of each sealing element.

During operation of the internal combustion engine, the exhaust pipe guides the exhaust heat flow 5 with a corresponding exhaust temperature. The tube portions 1, 3 that are connected to each other and sealed to each other by the sealing system of the present invention are provided with flange portions 9 or 11 that project radially outward with respect to the tube axis 7, respectively. These flange portions 9 and 11 jointly form a single ring-shaped flange 13, and the flange portions 9 and 11 include end faces 15 or 17 that face each other. In order to connect the tube parts 1, 3 to each other, the flange parts 9, 11 of the ring-shaped flange 13 are clamped together by suitable fastening means. This clamping means can be constructed in the usual way and is not shown. For example, as a tightening means, a tightening ring applied to the circumferential chamfered portions 25 of the flange portions 9 and 11 can be used.

各図面において、フランジ部９，１１間を封止するシール素子として、Ｃ字状の断面輪郭を有する金属製の成形リングシール３１を示す。上述のように、他の断面輪郭を有する金属製の成形リングシールまたは波形シール等を使用することができる。いずれにせよ、このようなシール素子は、フランジ部９，１１間に構成した収容空間３３内に、少なくとも部分的に収容する。図１〜３の各実施形態において、収容空間３３は、フランジ部１１の端面１７から軸線方向に窪ませて形成したリング溝４５によって構成し、このリング溝４５は、フランジ部９の端面１５に連結した際に、成形リングシール３１のためのチャンバを構成する。   In each drawing, a metal molded ring seal 31 having a C-shaped cross-sectional contour is shown as a sealing element for sealing between the flange portions 9 and 11. As mentioned above, metal shaped ring seals or corrugated seals having other cross-sectional contours can be used. In any case, such a sealing element is at least partially accommodated in the accommodating space 33 formed between the flange portions 9 and 11. In each embodiment of FIGS. 1 to 3, the accommodation space 33 is configured by a ring groove 45 formed by being recessed in the axial direction from the end surface 17 of the flange portion 11, and the ring groove 45 is formed in the end surface 15 of the flange portion 9. When connected, it forms a chamber for the molded ring seal 31.

本発明による封止システムにおいては、収容空間３３内に配置した成形リングシール３１のための付加的な断熱体として、各リング溝４５にカバー素子４７を配設する。カバー素子４７は、成形リングシール３１と、収容空間３３の最も熱負荷に晒される領域との間に断熱体を構成するように形成する。   In the sealing system according to the present invention, a cover element 47 is disposed in each ring groove 45 as an additional heat insulator for the molded ring seal 31 disposed in the accommodation space 33. The cover element 47 is formed so as to constitute a heat insulator between the molded ring seal 31 and the region of the accommodation space 33 exposed to the most heat load.

図１に示す実施例においては、カバー素子４７を、金属製の平坦リングとして構成し、この平坦リングは、成形リングシール３１と、対向するフランジ部材９の端面１５に接する端面１７との間に配設する。矢印４９によって示すように、この接合面は熱流５の影響を最も受ける箇所であり、カバー素子４７がここに位置することで保護効果が最大になる。   In the embodiment shown in FIG. 1, the cover element 47 is configured as a metal flat ring, and this flat ring is formed between the molded ring seal 31 and the end surface 17 in contact with the end surface 15 of the opposing flange member 9. Arrange. As shown by the arrow 49, this joint surface is the place most affected by the heat flow 5, and the protective effect is maximized when the cover element 47 is located here.

図２に示す第２実施例においては、カバー素子４７を、平坦リングの代わりにアーチ状のリング体を設ける。このリング体はリング溝４５内で、成形リングシール３１に対して、リング溝４５の開口側に隣接し、図１に示す実施例と同様に断熱体を構成する側を保護するだけでなく、さらに、リング溝４５の半径方向内方の壁、つまりを部分的に保護する。   In the second embodiment shown in FIG. 2, the cover element 47 is provided with an arched ring body instead of a flat ring. This ring body is adjacent to the opening side of the ring groove 45 with respect to the molded ring seal 31 in the ring groove 45, and not only protects the side constituting the heat insulator as in the embodiment shown in FIG. Further, the inner wall of the ring groove 45 in the radial direction, that is, the wall is partially protected.

図３に示す第３実施例においては、カバー素子４７は、成形リングシール３１の２側面に対する遮蔽体を成す。そのために、カバー素子４７は、角を有する断面輪郭を有するものとして形成され、断面輪郭の一方の辺は、図１の平坦リング体に対応するように、端面１７，１５の間の接合面に沿って延在する。他方の辺は、図２のカバー素子４７のアーチ状断面輪郭部分に対応するように、収容空間３３の熱流５に最も近い壁５からの遮蔽体を構成する。   In the third embodiment shown in FIG. 3, the cover element 47 constitutes a shield for the two side surfaces of the molded ring seal 31. For this purpose, the cover element 47 is formed as having a cross-sectional contour with corners, and one side of the cross-sectional contour is on the joint surface between the end faces 17 and 15 so as to correspond to the flat ring body of FIG. Extending along. The other side constitutes a shield from the wall 5 closest to the heat flow 5 of the accommodation space 33 so as to correspond to the arched cross-sectional contour portion of the cover element 47 of FIG.

上述したカバー素子４７の形態以外にも、例えば、シール素子を３側面で包囲するようなＵ字状断面輪郭を使用できること勿論である。いずれにせよ、リング溝４５内のカバー素子４７は、成形リングシール３１の、少なくともフランジ部９，１１の端面１５，１７側の部分を覆うように組み込む。また、好適には、さらに、成形リングシール３１の少なくとも熱に侵される危険性のある側面を、対応する形状のカバー素子４７により保護する。   In addition to the form of the cover element 47 described above, for example, a U-shaped cross-sectional contour that surrounds the sealing element on three side surfaces can be used. In any case, the cover element 47 in the ring groove 45 is incorporated so as to cover at least the end surface 15 and 17 side portions of the flange portions 9 and 11 of the molded ring seal 31. In addition, preferably, at least a side surface of the molded ring seal 31 that is at risk of being affected by heat is protected by a cover element 47 having a corresponding shape.
